Author: UrsFormat: MarkdownItexI have been adding some more (historical) references to the entry _[[quantum electrodynamics]]_ (also at _[[quantum field theory]]_, _[[S-matrix]]_ and _[[causal propagator]]_)

Author: DavidRobertsFormat: MarkdownItexSo far this is not the QFT version of QED? Just the quantum mechanics version? I learned not too long ago (from the graphic novel _[Feynman](https://www.brainpickings.org/2011/10/14/richard-feynman-graphic-novel-biography-ottoviani/)_!) that [Tomonaga](https://en.wikipedia.org/wiki/Shin%27ichir%C5%8D_Tomonaga) worked on his version of QED _in Tokyo during WWII._

Author: UrsFormat: MarkdownItexSorry, not sure what you are asking. "So far"? The entry is manifestly empty at the moment, except for references. The references speak about the quantum field theory called quantum electrodynamics (I am not sure what the "quantum mechanics version" of this would be?).
Maybe let's wait until there is some actual content in the entry...

Author: UrsFormat: MarkdownItexOh, I see. Yes, that's right: Dirac not only discovered the theory of a single electron (famously so), but he proceeded right away to study the corresponding field theory, too (not as famously, for some reason).
